Shedding light on water wheels: Photoinduced energy transfer is demonstrated between metal centers by a Ru II ) cyclodextrin “wheel” assembled in water. Os‐ and Ir‐complex guests with hydrophobic tails can be bound noncovalently in the cyclodextrin cavities. In such systems two‐way communication is possible as energy transfer can occur from the Ru core to the outer metal centers (purple arrows) or from the outer metal units to the Ru core (white arrow).
